FAQ LAN Transformer: WHD20K01G

What is the decisive PCB-footprint difference between WHD20K01G and other 20PIN dual-port DIP LAN transformers?

›

The decisive difference is its 2.54 mm pin pitch and 22.86 mm longitudinal pin span. Row spacing is 7.62 mm and the body is approximately 25.40 ± 0.50 mm × 10.00 ± 0.50 mm; 2.00 mm-pitch models commonly use an 18.00 mm longitudinal span. Do not reuse the hole pattern merely because both devices are 20PIN, dual-port parts.

How should the 1500 VAC, 60 s dielectric withstand requirement of WHD20K01G be written in an incoming-inspection specification?

›

Specify 1500 VAC between windings, a 1 mA leakage-current limit, a 60 s duration, and no insulation breakdown after the test. This is an isolation dielectric withstand test, not a continuous operating voltage. The incoming-inspection procedure should also define the sampling plan, voltage ramp-up and ramp-down method, and calibration status of the test equipment rather than stating only '1500 V withstand.'

How do the mechanical height and tube quantity of WHD20K01G affect enclosure design and material preparation?

›

The body height is 8.00 ± 0.50 mm and each tube contains 20 parts. Mechanical design must add PCB, solder-joint, and assembly tolerances to the body height. Purchasing and production should calculate partial-tube balances in multiples of 20 and confirm pin 1 orientation and the insertion-fixture clamping position on the first article.

What Certifications Does VOOHU Hold?

›

VOOHU is certified to ISO 9001:2015 and ISO 14001:2015 standards. Our products comply with RoHS, REACH, and CE requirements, ensuring high quality, environmental compliance, and reliable performance for global markets.
